The pulsations can be understood in termsof the recent revision of metal opacities, but the effects of rapidrotation and magnetic fields need further study. Observations in theUV and X-ray regions demonstrate that many B and Be stars show otheractivity, besides pulsation which is not yet understood. The reasonfor the enhanced mass loss in Be stars is a question which dominatesthe Symposium and which remains unanswered, although it is surely tobe found in activity at or near the photosphere coupled with rotation.It is shown that the geometry of the circumstellar envelopes around Bestars is indeed a flattened disk as they can now be opticallyresolved. The variability of radiatively-driven winds from O and Bstars are likely related to the rotation of the star. This underlinesthe central theme of the book: that the various phenomena seen inthese stars cannot be studied in isolation. . | | 出版日期 | Conference proceedings 1994 | | 关键词 | LOPES; photometry; spectroscopy; star; stellar | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-011-1030-3 | | isbn_softcover | 978-0-7923-3045-5 | | isbn_ebook | 978-94-011-1030-3Series ISSN 1743-9213 Series E-ISSN 2352-2186 | | issn_series | 1743-9213 | | copyright | Springer Science+Business Media Dordrecht 1994 |
